You guys are missing the point. If something ends up happening to me who is going to help me? If I ended up getting seriously sick in an accident no ex Jehovah's Witness is gonna help.
I understand how you're feeling. Any of us who grew up JW did so waiting for the next shoe to drop. We got used to the idea that we had a safety net and were part of a worldwide brotherhood and pitied anyone who wasn't part of it.
Apart from your immediate family and a handful of friends, the feeling of safety was an illusion. From what I've seen, when times of trouble come along, the congregation might be there with sympathetic words, mention you in a few prayers and offer a casserole or two but any real help came from family members or very close friends. Even that was short lived. It was still vital to have health insurance, social security, savings, be eligible for unemployment insurance and have a solid back-up plan. You can do this without having to sit through decades of mind numbing meetings listening to aggravating skewed logic. Why not spend the time working toward being self sufficient emotionally and financially.
So far you've (understandably) talked about others helping you...what others can do for you when you run into trouble. What do you have to offer others?
What if you met a man you were interested in and he told you his life plan was to join a club so that if he ran into trouble, he'd have someone to rely on. You'd likely think of him as a user and a weakling.
Gone are the days when a woman needs to be a dependent all of her life, whether it be emotionally or financially. I can see how going back to what is familiar might help you while you are getting yourself together but I wouldn't make being a JW your master plan. It's not fair to them and it's not fair to you.
If you want to go back to the JW's, do it for the right reasons. Like most avenues one uses to escape from reality, be it drugs, sex, alcohol, religion etc it will ultimately become a prison and eventually you'll have to the face reality you're running from, all at once. "Every form of refuge has it's price".
Scary as it may be at first, why not face reality on your own terms rather than waiting around for it to eventually catch up with you? Often the roaring lion (your fears) become a harmless kitten when you turn around and face them head on.
